Effect of coupling in steel/aluminium laminate subjected to tensile load

This project involves the study of coupling effects in steel/aluminium laminated structure when subjected to tensile loading. Three different cases of laminated structure are modelled and analysed using ANSYS. In the first case, the number of layers of constituent metals is increased while other asp...
